But WAMIA's president David Lock says with a number of groups running the facility some things are 'falling through the cracks'.

"Who's responsibility it is to do certain functions becomes unclear when there are a number of operators and then there's a lot of finger pointing. And so our joint decision was to look at how can we do this better," he says.

And Mr Lock fears that if changes aren't made soon, they risk losing customers.

"If we don't make a change, there is a risk that our suppliers or customers will become dissatisfied and look for alternatives," he said

It will be the end of the year before a decision is made on a new service provider, or making changes to the existing system.
